Under cloud environment, cloud service providers need to predict non-stationary workloads, and base prediction results to plan and execute fault-tolerance strategies in advance so as to ensure services' ability in fault-tolerance. High prediction precisions in services' workloads improve effectiveness of strategies such that service's fault-tolerance is advanced. In this paper, we propose a hybrid...
Chemically strengthened glass is widely used as a cover glass in consumer electronic devices, such as smartphones, tablets, and notebook computers. A cover glass protects the Liquid Crystal Display (LCD) in these devices from field abuse, such as scratches and impacts in device drop. Therefore, it is important to investigate the protective glass response under dynamic impact loading. The pendulum...
A new image recognition algorithm for a small creature—Caenorhabditis elgance is developed in this paper. This methods first use edge detection, binarization and other methods to get the body contours of C.elgance. Then using its body symmetry, C.elgance is recognized by comparing similarity of consecutive lines in image. The experimental result shows the high positioning accuracy and rapidity of...
This paper proposes a fast algorithm to reduce the high computational complexity of depth map coding in 3D-HEVC, which obstructs 3D video from the practical applications. Due to the special feature of depth maps, depth modelling modes (DMMs) were developed to keep sharp edges for depth map. Consequently, the 3D-HEVC encoder can improve the coding performance of synthesized views significantly. However,...
A new time-delay estimation method based upon Cubic spline interpolation and Area bary center algorithm that is well suitable for determining the time-delay between two noisy band-limited signals is introduced. Unlike conventional correlation algorithm, the new approach has the ability to optimally estimate any non-integral sample delay only using Cubic spline interpolation and Area bary center algorithm...
Reselection of composition service is one of the core research issues in the service computing field. Most of the existin-g researches for this problem are based on the assumption that the tasks involved are independent. However, in practical scenar-ios, the QoS of some candidate services have correlations with other services, which makes the corresponding tasks be correlated with each other. This...
Based on Lejeune Dirichlet allocation (LDA) model and multi-relationship topic model in Diagnosis and treatment of traditional Chinese medicine (TCM), the Symptom TCM Treatment Diagnosis (STTD) model is purposed to extract topic structure of symptom, TCM, treatment and diagnosis from TCM clinical datum. This paper uses Gibbs sampling to do parameters reasoning and confirms the optimal number of topics...
A new classification algorithm based on matrix degree of grey incidences for handwritten number recognition and natural image clustering is proposed in this paper. In order to recognize a handwritten numeral or to classify the type of images, we should extract the features that can describe the differences among all information efficiently ant first. Then the features matrix is build for the samples...
In this paper, an efficient and secure encryption scheme for JPEG2000 codestream is proposed. The scheme encrypts each codeblock contribution to a packet (CCP) and does not introduce superfluous JPEG2000 markers in the protected codestream. It achieves full information protection for data confidentiality, and maintains all the advanced features of the original JPEG2000 codestream such as error resilience...
Leaf color has been commonly used as an index for crop stress status diagnosis. We have developed a low-cost and non-destructive method that is easy to use to assess the health status of plants, based on the estimation of chlorophyll content of leaves using a portable digital camera. Relationships between chlorophyll content and leaf image color indices in the RGB and Lab* space with the comparison...
Laboratory anaerobic digestion studies were conducted to determine the effect of extracellular polymeric substances (EPS) on dewaterability of sludge (TS) with humus soil powder (HS) or not. In this study, an available stratification approach aimed at better understanding the factors influencing the sludge dewaterability was developed, which EPS were divided into soluble EPS and bound EPS by centrifuge...
There are complicated correlations among atomic Web services in a composite service. Considering the influence of such correlations on the quality of composite service is important to do service selection. Now, existing selection approaches don't consider this issue. Using the idea of division, a dot pattern based composite service selection approach is presented in this paper. The main idea of this...
Constructing optimal event correlation architecture is crucial to large-scale event services. It plays an instrumental role in detecting composite events requested by different subscribers in scalable and timely manner. However, events generated from different sources might have different time and priority requirements. In addition, the network links and correlation servers might have different bandwidth...
A novel grey relational operator is introduced that can be viewed as an extension of the well known gradient operator. In this approach, the factors of the referential sequence are the ideal non-noise pixel and its around pixels, and the factors of the comparative sequence are the local image pixel and its around pixels. The grey relational degree can be calculated according to the grey relational...
Driving is a complex man-machine process, color signal is an important factor for affecting driving fatigue. In the course of driving simulation, using different color signals to stimulate the drivers, through subjective questionnaires and measuring the changes in drivers?? physiological parameters, to research the changing law of the drivers?? heart rate, respiratory rate and other physiological...
